Weekly Ratings Update: April 10 – 23, 2017

Note: We missed publishing the update for April 10 to 16 period so we are integrating it in this post.

For four consecutive episodes (episodes 4 to 7), Whisper consistently gained 15 % in viewer ratings but finally broke that record when it achieved a whopping 16 % for its even episode last week. Needless to say, it is poised to lead the Monday-Tuesday competition until the end of its run. Meanwhile, Perfect Wife is also improving as shown by its CPP of 0.6 and 0.7 in the last two weeks.Rebel: Thief Who Stole the People, on the other hand, recorded a modest 0.3 CPP last last week but then lost 0.2 percentage point (pp). Its ratings dropped from 13.5 to 13.3 % last week.

Over at the cable networks, My Secret Romance premiered in April 17 but we couldn’t find any record of its ratings in Nielsen Korea’s website and other secondary sources online. For The Liar and His Lover, its performance did not improve. The ratings have been steadily dropping since episode 7. Its even episode last week recorded 1.433 %.

We can notice a drastic change in ratings for the Wednesday-Thursday time slot because of the presidential debate which aired on KBS1 on April 19. The ratings suddenly dropped to 7.7 % (from 11.6 % in April 13) for Mystery Queen, 4.4 % (from 7.1 % in April 13) for Radiant Office, and 6.1 % (from 8.5 % in April 12) for Saimdang, Light’s Diary. These values went back to normal on April 20 with Mystery, Radiant, and Saimdang recording a positive CPP of 3,2, 2.3, and 2.2, respectively.

For the weekend cable dramas, Chicago Typewriter failed to surpass its record in episode 2 and has been experiencing a drop in ratings since its second week. It recorded its all-time low last week of 1.920 % but recovered and obtained 2.236 % for the even episode. This is definitely not good news for tvN but the drama has still a chance to break tvN’s ratings slump in the following weeks. Meanwhile, Man to Man was off to a good start, pulling off the highest ever premiere rating for any JTBC drama at 4.055 %. This value barely improved though in the second episode, so we will have to see this week if it can really become as successful as its predecessor Strong Woman Do Bong Soon.

Tunnel is still doing pretty good, so it’s now safe to say that it is indeed following the success of Voice. On average, its ratings are increasing since episode 7. It broke its own record again last week as it achieved 5.413 %.

Me? Just an ordinary lad with an extraordinary (says this something called 'stereotype') habit of watching Korean dramas. It started with action-filled City Hunter and the rest, as they say, is history.
